Not necessarily. While a bowl labeled as "microwave and dishwasher safe" can handle the heat and agitation of the microwave and dishwasher, it does not automatically mean that it is oven safe as well.
The three main methods of heat used in the kitchen are microwave, oven, and stovetop. Microwave-safe bowls are designed to withstand the rapid heating and cooling that occurs in the microwave. Dishwasher-safe bowls can endure the high water temperatures and agitation during the dishwasher's cleaning cycles.
However, ovens operate at much higher temperatures than microwaves or dishwashers, and not all materials can handle that level of heat. Oven-safe cookware is specifically manufactured to withstand the high temperatures found in ovens, which can exceed 500°F (260°C) for conventional ovens and even higher for broiling.
If the bowl is not explicitly labeled as "oven safe," it's best not to use it in the oven. Attempting to use a bowl that is not oven-safe in the oven can lead to cracking, shattering, or even releasing harmful substances into your food.
To be sure about a bowl's oven safety, check the packaging, labels, or any included documentation for specific information regarding oven use. If you cannot find the information or are uncertain, it's safer to use the bowl only in the microwave and dishwasher, avoiding the oven entirely.
